Simpson 15/32 inch Plywood Sheathing Clips (PSCL) by Simpson are lightweight, precision-formed metal clips engineered to brace unsupported sheathing edges where plywood panels meet edge to edge without a rafter beneath for support. Designed for roof sheathing applications, these panel clips maintain a level, even plane across adjacent panels - reducing deflection and keeping the structure's surface properly aligned. A built-in 1/8 inch gap between panels accommodates natural wood shrinkage and expansion, making these clips a practical solution for any roof sheathing installation where panel edges would otherwise be left unsupported.

Key Features

• Sized for 15/32 inch panel thickness - matches standard 15/32 inch plywood sheathing for a secure, proper fit without modification
• Provides a 1/8 inch gap between adjacent panels - allows for natural wood expansion and shrinkage, helping prevent buckling or warping of the roof deck over time
• Braces unsupported sheathing edges - reduces deflection at panel edges even where no rafter is present, maintaining a flat, even surface across the structure
• 20-gauge steel construction - delivers reliable structural support while keeping the clip lightweight and easy to handle during installation
• Zinc galvanized G90 finish - corrosion-resistant coating suited for outdoor roofing environments and compatible with pressure-treated lumber applications
• Manufactured in the United States - produced domestically to consistent quality standards

Why This Product

• Solves the unsupported edge problem - when plywood sheathing panels meet without a rafter below, the PSCL clips hold those edges in alignment, preventing sagging or uneven roofing surfaces that can cause issues with the finished roof covering
• Built-in expansion gap means one less step - the 1/8 inch gap is engineered directly into the clip design, so installers do not need to manually space panels to account for wood movement
• G90 galvanized coating provides lasting protection - the zinc galvanized finish resists rust and corrosion in outdoor roofing conditions, extending the service life of the connection in wet or humid environments
• Straightforward sizing match - simply match the clip size to the panel thickness; these clips are specifically sized for 15/32 inch sheathing, eliminating guesswork on the jobsite

Frequently Asked Questions

Where exactly is the PSCL sheathing clip used on a roof?

The PSCL is used at panel edges where plywood sheathing panels meet edge to edge without a rafter underneath to support them. The clip slides over the edges of the two adjacent panels and holds them in alignment, bracing the unsupported joint and reducing deflection at that location.

Why does the sheathing clip have a 1/8 inch gap built in?

The 1/8 inch gap is designed to address the natural shrinkage and expansion that wood undergoes with changes in moisture and temperature. By spacing the panels slightly apart, the gap helps prevent buckling or distortion of the roof deck as the plywood panels move over time.

How do I choose the correct size sheathing clip for my panels?

Match the sheathing clip size to the thickness of the plywood panels being installed. This specific clip is sized for 15/32 inch panel thickness. Always refer to the sheathing manufacturer's installation instructions, as maximum spans may also be reduced for low-slope roofs or high uniform loads.

Is the G90 galvanized coating appropriate for outdoor roofing applications?

Yes. The G90 zinc galvanized coating provides corrosion resistance that is well suited to outdoor roofing environments where the clips may be exposed to moisture and humidity during and after installation. This coating also makes the clips compatible with pressure-treated lumber applications.
